A Brief History of Advanced Musculoskeletal Imaging Technologies

The advent of magnetic resonance imaging (MRI) and computed tomography, as well as ultrasound, vastly enhanced radiologists’ ability to study the anatomy and function of bones, muscles, joints, ligaments and tendons. Although researchers had experimented with tomography in the early 1900s and with MRI in the 1950s, advancements in the processing power and growing availability of computers  created new potential for these advanced imaging techniques in the 1960s.

CT Scanner

Computed Tomography

In 1969, an electrical engineer from the United Kingdom named Godfrey Hounsfield developed the first commercially viable CT scanner. One of these scanners was installed at Atkinson Morley Hospital in Wimbledon, England and the first patient brain scan was completed on October 1, 1971. Over the years, CT scanners have improved to perform scans more quickly, in higher detail and with lower doses of radiation. Numerous applications for CT in musculoskeletal imaging have been identified in the years since and ongoing research may result in CT scanners that are even faster and more efficient.

MRI Scanner

Magnetic Resonance Imaging

From the 1950s through the present, numerous researchers from across the globe contributed to advancements in MRI technology. MRI was first used, on a mouse, to produce a cross-sectional image in 1974. By the late 1970s, refined mathematical techniques allowed MRI scans to take seconds rather than hours and the first MRI body scan of a human was completed in 1977.

More powerful MRI machines with 1.5T magnets were introduced in the 1980s and these eventually led way to MRI machines with 3T magnets. Currently, researchers are exploring even stronger magnets and are continuing to identify new applications for MRI in musculoskeletal imaging.
